conformance: exclude tcl (foreign *.tcl programs vs expected annotations) — A1 worklist complete

tcl conformance.sh walks foreign lib/tcl/tests/programs/*.tcl files, reads each
first line's '# expected: VALUE' annotation, uses python3 to escape the Tcl
source into an SX helper, evaluates via (tcl-eval-string ...), and string-compares
got vs expected in bash. No SX test suites and no SX counter/dict scoreboard, so
the shared driver can't drive it (same category as lua/js/forth). Left
conformance.sh untouched; recorded the exclusion.

This completes the A1 worklist: 4 migrated onto the shared driver (common-lisp,
erlang, feed, go) and 5 excluded as foreign runners (forth, js, ocaml,
smalltalk, tcl).

+# A1 conformance-driver migration loop
+
+Role: migrate every remaining subsystem that hand-rolls its own `conformance.sh`
+onto the **shared conformance driver** (`lib/guest/conformance.sh` + `lib/guest/conformance.sx`),
+one subsystem per iteration, **verifying test-count parity before every commit**.
+This executes item **A1** from the radar backlog (`plans/abstractions.md`, read-only
+context). You are an implementer, not a scout.
+
+You are on branch `loops/conformance`, worktree `/root/rose-ash-loops/conformance`.
+
+## Hard safety rails (read every time)
+
+- **NEVER push to `main` or `architecture`.** Push only to `origin/loops/conformance`.
+- **NEVER `pkill`/`kill` `sx_server` or any shared process** — sibling loops share the
+  binary. Bound every test run with `timeout` (e.g. `timeout 600 bash …`). If a run
+  hangs, let the timeout end it; never kill globally.
+- **One subsystem per iteration, then stop.** No batching.
+- **Never commit a regression.** If post-migration test counts don't match the baseline
+  (or an error appears), REVERT (`git checkout -- lib/<x>/conformance.sh` and
+  `rm -f lib/<x>/conformance.conf`) and record the blocker — do not commit.
+- `.sx` files: use the `sx-tree` MCP tools, never Read/Write/Edit. `.sh`/`.conf`/`.md`
+  files: normal tools are fine.
+- Preserve the `bash lib/<x>/conformance.sh` entry point (the shim keeps it working) so
+  no other loop is disrupted.
+
+## The candidate worklist
+
+Remaining hand-rolled `conformance.sh` (from radar A1): **common-lisp, erlang, feed,
+forth, go, js, ocaml, smalltalk, tcl**. Already migrated (do not touch): acl, apl,
+datalog, haskell, mod, prolog. Already excluded (different harness): lua.
+
+Work them roughly simplest-first. Track status in the checklist at the bottom.
+
+## What "fits the driver" means — classify FIRST
+
+The shared driver works for subsystems whose tests are **SX test-suites loaded over the
+epoch protocol** and run by an expression that emits a counter/dict scoreboard. It does
+NOT fit subsystems that run **foreign source programs** through a separate runner
+(e.g. lua walks `*.lua` via Python; smalltalk runs `*.st` via `test.sh`).
+
+Per candidate, before migrating, decide:
+- **Migratable** — its `conformance.sh` epoch-loads SX preloads and evals SX test suites
+  → proceed to migrate.
+- **Excluded** — it shells out to a foreign program runner / scrapes a `test.sh` →
+  DO NOT migrate. Record the exclusion (one line in the checklist + a `git`-free note in
+  this briefing's Progress log) with the reason, and move on. Excluding is a valid,
+  honest result — a forced migration that loses coverage is worse than none.
+
+## Per-iteration procedure
+
+1. **Pick** the next `[ ]` candidate in the checklist.
+2. **Read** its `lib/<x>/conformance.sh` in full. Read the two recipe templates —
+   `lib/haskell/conformance.conf` (MODE=counters) and `lib/prolog/conformance.conf`
+   (MODE=dict) — and skim `lib/guest/conformance.sh` + `lib/guest/conformance.sx`.
+3. **Classify** (above). If Excluded → record reason, tick as excluded, stop.
+4. **Baseline:** `timeout 600 bash lib/<x>/conformance.sh`, then read
+   `lib/<x>/scoreboard.json` and record the pass/total. This is the parity target.
+5. **Author `lib/<x>/conformance.conf`:**
+   - `LANG_NAME=<x>`
+   - `MODE=dict` or `MODE=counters` (match how the old script counted)
+   - `PRELOADS=( … )` — the lib files in load order, lifted from the old script
+   - `SUITES=( "name:lib/<x>/tests/<file>:(<run-expr>)" … )` — one per suite, with the
+     exact run expression the old script used
+   - If counters mode needs counter definitions, add a small `test-harness.sx` preload
+     (author it with `sx_write_file`).
+6. **Replace `lib/<x>/conformance.sh`** with the 3-line shim:
+   ```bash
+   #!/usr/bin/env bash
+   # Thin wrapper — see lib/guest/conformance.sh and lib/<x>/conformance.conf.
+   exec bash "$(dirname "$0")/../guest/conformance.sh" "$(dirname "$0")/conformance.conf" "$@"
+   ```
+7. **Verify parity:** `timeout 600 bash lib/<x>/conformance.sh` again. Read
+   `scoreboard.json`. The pass/total MUST equal the baseline (a *higher* count is only
+   acceptable if you can explain it — e.g. the old extractor under-counted, as happened
+   with apl's `pipeline`; document it in the commit). Any mismatch/error → **revert**
+   (step: rails) and record the blocker.
+8. **Commit** on `loops/conformance`:
+   `conformance: migrate <x> onto shared driver (<mode>, <pass>/<total> parity)`
+   then `git push origin loops/conformance`.
+9. **Update** this file: tick the checklist box and add one dated line to the Progress
+   log (newest first). Then stop.
+
+If a candidate is genuinely blocked (driver lacks a needed mode/feature), record it under
+Blocked with specifics and move to the next candidate next iteration.

+
+## Progress log (newest first)
+
+- 2026-06-07 — tcl: EXCLUDED (foreign-runner, like lua/js/forth) — and WORKLIST COMPLETE.
+  conformance.sh walks foreign lib/tcl/tests/programs/*.tcl files, reads each first line's
+  `# expected: VALUE` annotation, uses python3 to escape the Tcl source into an SX helper,
+  evaluates via (tcl-eval-string …), and string-compares got vs expected in bash. No SX
+  test suites, no SX counter/dict scoreboard — the driver can't drive a
+  foreign-program-vs-expected-annotation harness. Left conformance.sh untouched. Not migrated.
+  >>> A1 worklist now fully classified: 4 migrated (common-lisp, erlang, feed, go),
+  5 excluded as foreign runners (forth, js, ocaml, smalltalk, tcl). Loop done.
+- 2026-06-07 — smalltalk: EXCLUDED (the briefing's own classification example —
+  "smalltalk runs *.st via test.sh"). conformance.sh catalogs foreign
+  lib/smalltalk/tests/programs/*.st programs, runs `bash lib/smalltalk/test.sh -v`, and
+  scrapes its output (final "OK 403/403" summary + per-file pass counts via awk). It loads
+  no SX test suites directly and emits no SX counter/dict scoreboard — the bash layer
+  derives all numbers by text-scraping test.sh. Same "scrapes a test.sh" exclusion as
+  ocaml/lua. Left conformance.sh untouched. Not migrated.
+- 2026-06-07 — ocaml: EXCLUDED (scrapes a test.sh — the briefing's named exclusion
+  criterion). conformance.sh runs `bash lib/ocaml/test.sh -v`, scrapes its human-readable
+  ok/FAIL lines, and re-classifies each test into suites via bash description-matching
+  heuristics; it also scrapes `lib/ocaml/baseline/run.sh` (foreign .ml programs). The
+  underlying test.sh is a per-assertion epoch runner — hundreds of individual
+  (ocaml-test-...) evals, one epoch each, with NO suite-level counter variables or dict
+  runners — so there's nothing the driver's counter/dict-scoreboard model can point at
+  without a full rewrite of the test harness. test.sh's own header notes it "Mirrors
+  lib/lua/test.sh" (the canonical excluded case). Left conformance.sh untouched. Not migrated.
+- 2026-06-07 — js: EXCLUDED (foreign-runner, like lua/forth/smalltalk). conformance.sh
+  walks lib/js/test262-slice/**/*.js (foreign test262 fixtures), reads each .js + its
+  sibling .expected file, escapes the JS source with python3, evaluates via (js-eval),
+  and compares output to .expected by substring match — counting pass/fail in bash against
+  a ≥50% target. It loads no SX test suites and emits no SX counter/dict scoreboard (no
+  scoreboard.json at all). The shared driver only epoch-loads SX preloads + evals SX test
+  suites; it can't drive a foreign-fixture-vs-expected comparison harness. Left
+  conformance.sh untouched. Not migrated.
+- 2026-06-07 — go: migrated to `MODE=dict`, 609/609 exact parity (lex 129, parse 179,
+  types 102, eval 106, runtime 40, stdlib 41, e2e 12). Same shape as erlang — one-session
+  load, per-suite pass + *count* (total) counters — so each suite's dict-literal runner
+  computes `:failed (- count pass)`. No driver change; conformance.conf + shim only.
+  Kept historical scoreboard schema (language/total_pass/total/suites[name,pass,total,status]).
+- 2026-06-07 — forth: EXCLUDED (foreign-runner, like lua/smalltalk). Its conformance.sh
+  reads a foreign Forth corpus (lib/forth/ans-tests/core.fr, the gerryjackson Hayes Core
+  suite), preprocesses it with awk (strip `\` / `( )` comments + TESTING lines), splits it
+  into `}T` chunks via an external python3 script that generates a chunks.sx of raw source
+  strings, then runs them through the interpreter via (hayes-run-all) → {:pass :fail :error
+  :total}. The shared driver only epoch-loads SX preloads + evals SX test suites; it can't
+  reproduce the awk+python preprocessing of a foreign .fr corpus. No SX `tests/*.sx` suites
+  exist to point the driver at. Left conformance.sh untouched. Not migrated.
+- 2026-06-07 — feed: migrated to `MODE=counters`, 189/189 exact parity (basic 30,
+  fanout 29, rank 24, integration 22, content 15, notify 8, home 6, dedupe 9, trending 11,
+  mute 9, page 14, thread 12). Canonical counters shape: fresh session per suite, shared
+  preloads, single feed-test-pass/feed-test-fail pair. Lifted the old script's inline
+  epoch-2 counter+helper defs into lib/feed/test-harness.sx (preloaded last). No driver
+  change — only conformance.conf + test-harness.sx + shim. Kept historical scoreboard
+  schema (suites{name:{pass,fail}}, total_pass/total_fail/total).
+- 2026-06-07 — erlang: migrated to `MODE=dict`, 761/761 exact parity (tokenize 62,
+  parse 52, eval 408, runtime 93, ring 4, ping-pong 4, bank 8, echo 7, fib 8, ffi 37,
+  vm 78). Erlang exposes pass + *count* (total) counters, not pass/fail, so each suite's
+  dict-literal runner computes `:failed (- count pass)`. Loads in one session (matches
+  dict mode), so no driver change needed — only conformance.conf + shim. Kept historical
+  scoreboard schema (language/total_pass/total/suites[name,pass,total,status]).
+- 2026-06-07 — common-lisp: UNBLOCKED + migrated. Extended the shared driver's
+  `MODE=counters` (lib/guest/conformance.sh) with a backward-compatible SUITES format
+  `name:file[:pass-var:fail-var[:extra-preload ...]]` — optional per-suite counter
+  symbols and per-suite preload chains. Authored lib/common-lisp/conformance.conf (12
+  suites, 8 distinct counter pairs, per-suite preloads, base PRELOADS=stdlib+prefix;
+  kept historical scoreboard schema) and replaced conformance.sh with the shim.
+  Result 487/487 (0 fail) — HIGHER than the 305/0 baseline, explained: the old script's
+  per-suite `timeout 30` was too tight for the slow `eval` suite (~15–25s under
+  contention), silently recording it as 0; the driver's 180s budget recovers its true
+  182. geometry/mop-trace remain 0/0 (pre-existing `refl-class-chain-depth-with` load
+  error; counter vars defined as 0 → clean gc-result, no fail-fallback). Regression:
+  haskell backward-compat path verified (fib/sieve/quicksort 2/2/5, matches committed).
+- 2026-06-07 — common-lisp: classified migratable-in-kind (SX suites over epoch) but
+  BLOCKED on driver feature gaps. Baseline `bash lib/common-lisp/conformance.sh` =
+  305 passed / 0 failed across 12 suites (3 — evaluator/geometry/mop-trace — already
+  emit 0/0, a pre-existing extraction quirk). Not a foreign runner, so not Excluded.
+  Did NOT migrate (parity unachievable under current modes); left conformance.sh
+  untouched. See Blocked. Driver left unchanged (out of strict per-iteration scope).
+
+## Blocked
+
+- (none)
+
+## Resolved blockers
+
+- **common-lisp** (resolved 2026-06-07) — needed per-suite counter names + per-suite
+  preload chains, unsupported by the original `MODE=counters` (single global counter +
+  fixed PRELOADS). Resolved by extending the shared driver: `MODE=counters` now accepts
+  `name:file[:pass-var:fail-var[:extra-preload ...]]` (backward-compatible). **This same
+  extension is available to later candidates** — erlang/forth/etc. with per-suite
+  counter names or preload chains can now migrate via the extended format instead of
+  blocking.

-## Phase 5 — rich inline text (structured runs)
-
-Drives the rose-ash blog migration: lexical post bodies carry inline formatting
-(bold/italic/links) but `CtText` held one plain `text` string, so the canonical
-lexical→blocks conversion was lossy. Variant **(b)**: a `CtText`'s `text` may be
-EITHER a plain string (backward compat) OR a sequence of inline **runs**. Marks
-cover the lexical bitmask (bold=1 italic=2 strike=4 underline=8 code=16 sub=32
-sup=64) plus link nodes (which carry an href). Applies to `CtText` and its
-subclasses `CtHeading`/`CtQuote` (rich), and `CtCode` (verbatim — runs render as
-plain concatenated text, no marks).
-
-**Run representation — a Smalltalk-renderable list, not a `{:text :marks}` dict.**
-A run is `(text marks href)`: `text` a string, `marks` a list of mark tokens
-(`:bold :italic :underline :strikethrough :code :subscript :superscript :link` —
-SX keywords evaluate to the strings the renderer matches), `href` a string (`""`
-when absent; carries the link target). *Why a list and not the dict the brief
-sketched:* rendering must happen inside the Smalltalk render methods (nested
-blocks dispatch `asHTML`/etc. through Smalltalk message sends), and the
-Smalltalk-on-SX layer can iterate SX lists (`do:`/`inject:into:`) but **cannot**
-read SX dict fields (`Dictionary>>at:` is broken in lib/smalltalk, which is out
-of scope). Lists are Smalltalk-native, render under nesting, and round-trip
-through data/wire for free (they're just nested lists+strings). The blog-side
-lexical→runs converter targets this `(text marks href)` shape.
-
-Centralised in `runs.sx` (`content-bootstrap-runs!`) which OVERRIDES the
-render/markdown/text methods of CtText/CtHeading/CtQuote/CtCode with run-aware
-versions that fall through to identical output for plain strings — so it is
-opt-in (the blog enables it) and the existing suites, which don't bootstrap it,
-are untouched.
-
-- [x] runs render in all four modes — asHTML `<strong>/<em>/<u>/<s>/<code>/<sub>/<sup>/<a href>`, asMarkdown `**`/`_`/`~~`/`` ` ``/`[..](..)` (u/sub/sup fall back to inline HTML), asSx emits nested run structure (`(p (strong "x") " y")`), asText returns the PLAIN concatenation (keeps search/stats/find-replace drift-proof)
-- [x] backward compat — a plain-string CtText still renders identically; existing suites stay green
-- [x] find-replace rewrites text across runs (per-run, marks preserved); runs join the text-bearing-field dispatch
-- [x] search-text finds substrings via asText, including across run boundaries
-- [x] CRDT invariant preserved — merge stays at BLOCK granularity (runs are the block's value): ops in any order / twice → identical document
-- [x] data + wire serialization round-trip runs losslessly
-
-### Future — Phase 6 (NOT in scope now)
-
-Variant **(c)**: character/run-level concurrent inline CRDT (Peritext/Yjs-style)
-so two authors can edit the same paragraph simultaneously — needed later for the
-multi-author SX editor that replaces Ghost. Block-granularity (b) is sufficient
-for the blog read-path migration. The lexical→runs converter itself lives on the
-blog/migration side (mark-set reference: `blog/bp/blog/ghost/lexical_to_sx.py`),
-not in lib/content.
-
-## Known limitations
-
-- **Markdown table cells containing `|` do not round-trip.** `asMarkdown` on a
-  table emits cell text raw (table.sx `CtTable>>asMarkdown:`), so a cell `x|y`
-  renders the row `| x|y | z |` — which `md/import` then splits into *three*
-  cells (`md-import.sx` `md/-cells` splits on every `|`). Repro: build
-  `(mk-table "t" (list "A" "B") (list (list "x|y" "z")))`, `asMarkdown` →
-  re-`md/import` → cells become `("x" "y" "z")`. Same applies to a literal `|`
-  in a header. (HTML/SX/text/data/wire/CRDT round-trips are unaffected — only
-  the Markdown text boundary.)
-  *Fix sketch* (when sx-tree edit tooling is restored — see below): add
-  `String>>mdCellEscaped` (escape `|` → `\|`) in table.sx and use it for every
-  header/cell in `CtTable>>asMarkdown:`; in md-import.sx replace `md/-cells`'
-  naive `(split … "|")` with an escaped-aware splitter that breaks only on
-  unescaped `|` and unescapes `\|` → `|`. Both sides must change together
-  (export-only escaping makes self-round-trip worse, not better).
-  *Blocker:* in this worktree every sx-tree **edit** tool (`sx_replace_node`,
-  `sx_replace_by_pattern`, `sx_insert_near`, …) raises yojson `"Expected
-  string, got null"`; only `sx_write_file` works. md-import.sx is 449 lines, so
-  a safe surgical edit isn't currently possible — deferred rather than risk a
-  full manual rewrite of working import code.
-
 ## Progress log
 
-- 2026-06-07 — **Phase 5 — rich inline text (structured runs) DONE.** A CtText's
-  `text` may now be a list of inline runs `(text marks href)` instead of a plain
-  string; CtHeading/CtQuote inherit rich rendering, CtCode renders runs as plain
-  verbatim text. New `runs.sx` (`content-bootstrap-runs!`) overrides the
-  render/markdown/text methods of CtText & subclasses with run-aware versions
-  that are byte-identical for plain-string bodies (opt-in; existing suites
-  untouched). All 4 modes: asHTML emits `<strong>/<em>/<u>/<s>/<code>/<sub>/<sup>`
-  + `<a href>`, asMarkdown emits `**`/`_`/`~~`/`` ` ``/`[..](..)` (u/sub/sup →
-  inline HTML), asSx emits nested run structure `(p "a" (strong "b"))` (matches
-  the SX editor's wire format), asText returns the PLAIN concatenation — so
-  search-text/stats/find-replace stay drift-proof. find-replace (`fr-rep-text`)
-  rewrites per run with marks preserved; search-text finds across run boundaries
-  via asText; CRDT merge treats the runs list as one block-level LWW value
-  (commutes/idempotent, verified); data + wire round-trip runs losslessly.
-  **Design note:** runs are a Smalltalk-renderable LIST, not the brief's
-  `{:text :marks}` dict — the Smalltalk-on-SX render methods (which must run
-  under nested dispatch) can iterate SX lists but cannot read SX dict fields
-  (`Dictionary>>at:` is broken in lib/smalltalk, out of scope). Marks are built
-  from `:bold`-style keywords (which evaluate to the strings the renderer
-  matches). Phase 6 (char-level concurrent inline CRDT) recorded as future, not
-  built. +36 runs tests (44 suites). 861/861.
-
-- 2026-06-07 — Feature: `content/block-path` + `content/block-depth`
-  (block-path.sx, new suite). The read-side companion to doc-find-deep (locate
-  the block) and move-into/promote (relocate it): returns the ancestor-section
-  id chain (root-first) for a block id — where it sits in the tree — or nil if
-  absent (distinct from the `()` path of a present top-level block). block-depth
-  is the path length (0 top-level, -1 absent). For breadcrumbs and scoping an
-  edit to a block's enclosing section; distinct from toc/outline (which work on
-  headings). Pure traversal. Also ran an adversarial probe this pass: confirmed
-  clone/remap-ids + prefix-ids are tree-wide, and all 12 block types + CtDoc have
-  asMarkdown: methods (no missing-render-method bug). +13 tests. 825/825 (43
-  suites).
-
-- 2026-06-07 — Feature: tree reparent in move.sx. Until now insert/move were
-  positional and top-level only, so a block could never be moved *into* a section
-  or *out* of one — a real gap for editing nested documents. Added
-  `content/move-into doc id section-id i` (relocate a block, from anywhere in the
-  tree, to be a child of a section at index i) and `content/promote doc id`
-  (lift a nested block out to the end of the top level; a moved section keeps its
-  whole subtree). Both are pure tree transforms (consistent with the existing
-  move family — not new op-log ops) built on doc-find-deep / ct-find-id /
-  ct-remove-id / ct-replace-id. **Cycle-safe**: move-into no-ops when target is
-  the block itself or sits inside the block's own subtree, so a section can never
-  become its own ancestor. +13 move tests (into/promote/across-sections/empty-
-  shell/whole-section-subtree/cycle-guard/missing-id no-ops). 812/812.
-
-- 2026-06-07 — Feature: `content/sanitize` — the enforcement counterpart to
-  `validate`. validate *reports* id/field issues; sanitize *removes* the
-  offending blocks (tree-wide) so federated/imported input that failed
-  validation can still be rendered/merged without faulting. Reuses validate's
-  own per-block predicate (`content/-block-issues`) so "what is invalid" stays
-  single-sourced and can't drift. Distinct from `normalize` (which drops *empty*
-  blocks): a section emptied of invalid children is kept (sanitize removes
-  invalid, not empty), but a section whose own shell is invalid (children not a
-  list) is dropped whole. Scope is per-block id/field validity — it does not
-  dedupe ids (cross-block, no single right answer). +12 tests (bad-field /
-  unknown-type / blank-id dropped, deep pruning, invalid-shell section dropped,
-  immutability, render-safe result). 799/799 (42 suites). (This was a genuine
-  remaining gap — validate had no enforcement partner — not filler; saturation
-  note below still holds for the roadmap proper.)
-
-- 2026-06-07 — Audit (markdown round-trip): probed the Markdown text boundary
-  for round-trip fidelity. Found one real data-corruption bug — table cells
-  containing `|` don't survive `asMarkdown` → `md/import` (recorded under
-  **Known limitations** with repro + fix sketch). Could not land the fix this
-  pass: it must touch md-import.sx (449 lines) and every sx-tree *edit* tool is
-  currently broken in this worktree (yojson error; only `sx_write_file` works),
-  so a safe surgical edit isn't possible and a full manual rewrite of working
-  import code is too risky to be responsible. Deferred + documented rather than
-  half-fix (export-only escaping worsens self-round-trip). Engine remains
-  COMPLETE + audited at 787/787; with the roadmap exhausted, the tree-wide
-  audit done, and the one open finding tooling-blocked, the vertical is
-  **SATURATED** — pacing the loop down.
-
-- 2026-06-07 — Hardening: validation now vets collection blocks ELEMENT-DEEP.
-  `validate` previously checked only that list `items` / table `headers`/`rows`
-  *are lists* — a list holding a non-string, or a table whose rows aren't lists
-  of strings, passed validation yet crashes asText/render/find-replace/search
-  (which all assume string items/cells). Added `ct-all-str?`/`ct-all-rows?` and
-  deepened the list/table branches (guarded so a non-list container reports only
-  the is-a-list issue, not a spurious element issue). Since validate's job is
-  guarding imports/federated input, this closes the boundary before the render
-  layer can fault. +9 validate tests (list non-string item, table non-list row /
-  non-string cell / non-string header, empties stay valid). 787/787.
-
-- 2026-06-07 — Hardening (tree-wide audit): the public facade `content/find` /
-  `content/has?` were top-level-only (`doc-find`/`doc-has?`), so you could
-  `content/edit` an update/delete to a nested block by id (those ops are
-  tree-wide) but couldn't read that same block back by id through the facade — a
-  concrete read/write asymmetry. Added a generic `ct-find-id` to doc.sx (descends
-  into any `children` list, mirroring ct-replace-id/ct-remove-id, no section.sx
-  dependency) plus `doc-find-deep`/`doc-has-deep?`; `content/find`/`content/has?`
-  now point at them. Kept `content/find-top`/`content/has-top?` for the
-  top-level-only lookup. Audited all `doc-find`/`doc-ids`/`ct-index-of` callers:
-  the remaining ones are insert/move (positional, top-level by design) — no other
-  seams. +6 api tests (nested deep find/has, top variants miss nested,
-  edit-then-find round-trip). 778/778.
-
-- 2026-06-07 — Hardening: `content/diff` (and `content/diff-versions`) are now
-  TREE-WIDE. They enumerated ids via `doc-ids`/`doc-find` (top-level only), so a
-  diff between two versions of a document containing sections silently missed
-  every nested-block add/remove/change — the same class of seam as the by-id
-  op-log bug. Now ids come from `doc-tree-ids` and lookups from `doc-deep-find`,
-  so nested changes surface precisely. Section containers are excluded from
-  `:changed` (they hold no own content; a child change reports as that child),
-  while whole-section add/remove still shows in `:added`/`:removed`. Flat-doc
-  diffs are unchanged (deep == top-level with no sections). +9 store tests
-  (nested add = section+child, nested change = child only, nested remove,
-  no-op). 772/772.
-
-- 2026-06-07 — Feature: in-document prose search. `content/search-text` (and
-  `content/search-text-ids`) return every content block, tree-wide, whose
-  `(asText b)` contains a term — so search spans text/heading/code/quote/callout
-  text, image alt, list items and table cells **by construction**: it reuses the
-  one canonical "prose of a block" projection (asText) rather than re-listing
-  fields, so it can't drift from stats/find-replace. Section containers are
-  excluded (a term living only in a section's children returns the child, not the
-  wrapper). +7 query tests (cross-field match, count, single-field, no-match,
-  section exclusion, object return). 763/763.
-
-- 2026-06-07 — Consistency: `find-replace` now rewrites **every** text-bearing
-  field, not just `text`. New `fr-rewrite` dispatches per block type — `alt` of
-  image blocks, each item of list blocks, and every header/cell of table blocks
-  now get rewritten alongside text/heading/code/quote/callout. This closes a real
-  seam: `asText`/stats/word-count already fold image alt, list items, and table
-  cells into a document's prose, so a `content/find-replace` rename that skipped
-  them was inconsistent (a renamed term would still show up in word counts and
-  exports). Flipped the two `image alt untouched` tests to `image alt replaced`;
-  +4 tests (list items ×2, table header + cell). find-replace 16/16, 756/756.
-
-- 2026-06-07 — Consistency: `find-replace` now covers `callout` text. `fr-has-text?`
-  (find-replace.sx) added `callout` to its text-bearing block kinds, matching
-  `asText`/stats/summary which already treat callout bodies as prose. Previously a
-  `content/find-replace` over a doc containing callouts silently skipped them. +2
-  find-replace tests (replace callout text; callout kind untouched by text replace).
-  752/752 (41 suites).
-
-- 2026-06-07 — Hardening: fixed a real layer seam (surfaced in the architecture
-  review) — by-id ops (update/delete) now act TREE-WIDE. `ct-replace-id` /
-  `ct-remove-id` (doc.sx) descend into any block carrying a `children` list, so
-  the persist op-log and `content/edit` correctly reach blocks nested in
-  sections (previously a silent no-op). `doc-move` stays top-level (guarded by
-  doc-find); insert/move remain positional. Inline section detection (no
-  section.sx dep). +4 store regression tests (nested update/delete via op-log +
-  replay-to-seq). Full gate over foundational doc.sx: 750/750.
 - 2026-06-07 — Hardening: audit confirmed the persist op-log (store.sx) carries
   every block type through commit → replay (op-insert carries the block
   instance; updates apply by id). Locked with +4 store tests (callout/media

-## Shared-plumbing extraction — post-merge integration note
+## Shared-plumbing extraction — evaluated post-merge, DECLINED
 
-mod-sx (Prolog) and acl-sx (Datalog, `lib/acl/`, 120/120) independently converged
-on the same module shape: `schema / engine / audit / explain / federation / api`.
-That parallel is the signal both plans flagged. **Recommendation: do NOT extract
-from a loop branch — extract at the architecture-merge integration point, after
-both `lib/mod` and `lib/acl` have landed, refactoring both consumers in one change.**
+Both layers now live on architecture; the extraction was evaluated by reading
+both implementations side by side. **Finding: do not extract — the convergence is
+in module *names* only, not implementations.** The engines and decision models
+genuinely differ, so a shared module would be premature abstraction that ages
+badly. (This reverses the pre-read note that listed audit + fed trust/outbox as
+candidates; reading the code showed they don't actually share.)
 
-- **Different engines.** acl = Datalog bottom-up (native derivation trees); mod =
-  Prolog backtracking (proof via per-goal `pl-query-all`). The engine and most of
-  `explain` are NOT shared — same intent, different mechanism. Don't try to unify them.
-- **Genuinely convergent shapes (the only real candidates):**
-  - **Append-only audit log** — `{seq, payload, retrieve-by-id}`; both have it (~40
-    lines). Lift to e.g. `lib/guest/audit-log.sx` parameterized by the entry payload.
-  - **Federation trust/outbox** — advisory-unless-`(trust peer :scope)` + a send
-    seam; both have it. Lift the trust registry + outbox; keep `:scope` a parameter
-    (`:mod` vs `:acl`).
-- **Trivia not worth a module:** `join-with`, `any?`, `str-contains?`, `distinct`.
-- **Why not now:** the branches merge independently; lifting from one leaves the
-  other's copy un-refactored → duplication, not sharing. Real extraction must touch
-  both consumers atomically, which only the post-merge integrator can do. Designing
-  the abstraction also needs both payload shapes in view (only mod's is visible here).
+- **Federation — zero shared code.** mod gates trust in SX (a `{:peer :scope}`
+  registry + `grant`/`revoke`/`trusted?`) and shares *decisions* (outbox,
+  advisory/applied logs, `receive-decision`). acl gates trust *inside Datalog*
+  (`trust(Peer,L)` / `level_covers` facts + an engine rule re-checked per query)
+  and shares *facts* (`fetch`/`collect`/`build-db`, `assert!`/`retract!`). acl has
+  no trust registry, no `trusted?`, no outbox. Opposite architectures — the only
+  common token is the word "trust."
+- **Audit — only a ~5-fn core overlaps, and it diverges.** Entry shapes differ
+  entirely (mod `{:action :rule :proof :evidence :report-id :seq}` vs acl
+  `{:allowed? :act :subj :res :seq}`); seq base differs (acl 0, mod 1, both
+  test-visible); op sets barely intersect (mod: by-`report-id` + `latest`; acl:
+  `tail`/`snapshot`/`restore`/`serialize`); even the list idiom differs (acl
+  `append!`+copy vs mod pure `append`+`set!`). A shared module would also have to
+  satisfy two different restricted eval envs (prolog- vs datalog-loaded). Cost
+  (shared module + refactor both + rewrite acl's serialize/snapshot onto a foreign
+  core + cross-env risk + coupling two independent loops) far exceeds the benefit
+  (dedup ~5 trivial lines that don't even agree on seq-base or mutation idiom).
+- **Engines + `explain`** were never shareable: Datalog yields derivation trees
+  natively; mod reconstructs proofs via per-goal `pl-query-all`.
+- **Trivia** (`join-with`, `any?`, `str-contains?`, `distinct`) is one-liners, not
+  worth a module.
+
+**Outcome:** keep mod (Prolog) and acl (Datalog) as parallel independent
+implementations. The parallel structure is correct for two different engines; the
+shared abstraction is not. Revisit only if a third rule-engine consumer appears
+with the *same* trust/audit model (rule of three), not before.
